Title: Effects of Intensive Forest Management on Amphibians and Reptiles of Vancouver Island

Year: 1986

Author(s): K. L. Sadoway

Type: Report (published)

Description:
Introduction: Amphibians and reptiles are cryptic animals and generally go unnoticed. Of the 19 amphibians and 18 reptile species known to occur in British Columbia, nine amphibian and seven reptile species are indigenous to Vancouver Island. An additional three amphibian species have been introduced to the island. The economic importance of these animals is linked largely to the pet trade. Amphibians are extensively used for biological research and frog legs continue to be a popular gastronomic fare in eastern Canada and the USA. The market demand for snakeskin leather is also increasing. Ecologically, amphibians are an important food source for a variety of fish, reptiles, birds and mammals. The amphibians' role in controlling forest insect pests has been stated; however, the extent of this role and its economic value have not been studied. Reptiles play the role of both predator and prey. In this analysis on the effects of intensive forest management on amphibians and reptiles, only indigenous species will be discussed in detail. Information on the three introduced amphibian species is limited to species distibution and its potential effects on indigenous species.

Title: Components of Variation in Nuptial Calls of the Least Sandpiper (Calidris minutilla; Aves, Scolopacidae)

Year: 1986

Author(s): Edward H. Miller

Type: Journal Article

Description:
Unpaired male least sandpiper (Calidris minutilla) emitted three main kinds of calls to attract mates and in sexutal or agonistic interactions. The call types varied slightly across the nesting range (samples from British Columbia, Yukon Territory, Manitoba and Nova Scotia). One call type, analyzed in most detail, was given in long rhythmic series during aerial displays. Tape recordings of 2,250 calls from 80 m ales were analyzed using four measurements on temporal characteristics and eight on frequency. Most of the variance (59-82% for the 12 characters) was attributable to variation among males, less to cells (13-41%), and least to locality (0-9%); only one variable differed significantly among geographic samples. Temporal characteristics varied more than frequency characteristics, with coeeficients of variation (Vs) averaging 4 to 9% for the former and 2 to 3% for the latter. Vs were significantly heterogeneous across characters for each locality but variability profiles were very similar among localities. No Vs differed significantly among geographic samples. The extreme geographic uniformity in call structure, univariate and multivariate variation, variance components, and correlational relationships among call variables, was unexpected. Comparative studies using similar quantiative techniques are needed to assess the generality of the findings.

Title: Intensive forestry effects on Vancouver Island deer and elk habitats. Problem Analysis.

Year: 1985

Author(s): J.B. Nyberg

Type: Government document

Description:
This problem analysis was requested by the Technical Working Group directing the integrated Wildlife - Intensive Forestry research program on Vancouver Island. Its goal is to evaluate research priorities concerning the ways in which intensive forest management will affect habitat values for deer and elk. Other studies will focus on the ways these animals use their habitats e.g. habitat selection and population responses), and will be coordinated with the forestry/habitat investigations that will follow from this problem analysis.

Title: Forest crowns, snow interception and management of black-tailed deer winter habitat.

Year: 1985

Author(s): R.S. McNay

Type: Government document

Description:
The phenomenon of snow interception by forest stands is examined. Interception relationships extracted from literature are evaluated for their applicability to the silvicultural and climatic conditions of south coastal British Columbia. Hypothesis tested address: 1) the prediction of snow interception, 2) comparisons of heterogeneity in snow interception between second-growth and old-growth forests, and 3) how interception and interception efficiency vary depending on forest crown completeness and storm size. General relationships regarding snow interception under continental conditions were found to hold in coastal conditions, but relationships between crown completeness and interception were weak. Storm size and melt are identifies as confounding factors in making predictions about snow inerception based on stand crown completeness.

Title: Deer movements and habitat use during winter

Year: 1985

Author(s): J.B. Nyberg; D. Doyle; L. Peterson

Type: Government document

Description:
The research topic identified as having the highest priority was how forestry practices could be used to create suitable black-tailed deer and Roosevelt elk winter habitat in young-growth stands. This working plan provided details of the research to be conducted on deer winter habitat during the winter of 1984/85.

Title: Female size and nest depth in coho salmon (Oncorhynchus kisutch)

Year: 1984

Author(s): Eric P. Van der Berghe; Mart R. Gross

Type: Journal Article

Description:
Nest depth was strongly correlated with female size in coho salmon. Since nests of different-sized females are at different depths, they are differently vulnerable to destruction by floods and to other females competing for the same nest sites.

Title: Dynamics of shallow-water populations of Octopus dofleini

Year: 1984

Author(s): E. B. Hartwick; R. F. Ambrose; S. M. C. Robinson

Type: Journal Article

Description:
Octopus dofleini is a common inhabitant of shallow subtidal communities in the Northeast Pacific. The abundances of octopuses at two sites monitored since 1977 have fluctuated greatly during this period. The populations reached high abundances in mid-summer an, during some years, mid-winter. The highest abundances at the two sites did not coincide. There was a constant influx of new octopuses into both study sites, with the greatest immigration occurring in early summer. The octopuses captured spanned a wide range of wieghts every month, with no clear size classes or seasonal trends in size. The weights of newly-captured octopuses, however, did differ between the sexes and seasons: males weighed more on the average than females, and male weight decreased from winte rto fall while female weights did not change. O dofleini appeared to recruit throughout the year; the smallest octopuses occurred between May and November and the greatest number of small octopuses was found in July and August in most years. Females predominated at both study sites throughout the year. However, males predominated among octopuses caught in traps at nearby locations, suggesting that the skewed sex ratios were due to behavioral differences between the sexes.

Title: Den Utilization and the Movements of Tagged Octopus dofleini

Year: 1983

Author(s): E. Brian Hartwick; Richard F. Ambrose; Shawn M. C. Robinson

Type: Journal Article

Description:
Individual Octopus dofleini in a shallow-water population in British Columbia, Canada, were tagged and their movements monitored at biweekly intervals for one year. Octopuses moved into the study areas throughout the year and stayed up to 6.5 months (mean = 57 days). Immigration rates were highest in July/August and November/December. Most octopuses occupied the same shelter for at least one month. Octopuses that changed dens within the study area moved an average of 13.2m. More than one-fourth of the octopuses were absent for more than a month,then recaptured at the same site. Monthly departure rates were extremely variable, and could not be distinguised from random. These data indicate a pattern of large-scale movement interspersed with periods of residence in a relatively small area; evidence for seasonal migrations in this populations are also evaluated.
